P0EA5DC/DC Converter B Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0EA5 says that a second DC/DC converter, B, does not deliver what it is asked to, for example the commanded output voltage or current, although its sensors give no circuit fault. FCA documents it as DC/DC Converter 2 Performance for the 2019 Jeep Cherokee (KL) with the 3.2 litre V6 and engine start/stop: PCM flash bulletins 18-023-19 REV. B and 18-077-22 list it with P0EA6 and with communication codes for converter control modules A and B, alongside restart problems after a stop phase. The fix there is new PCM software, done with a charger keeping the battery between 13.2 and 13.5 V. Ford's equivalent test for converter A (P0A94) compares calculated and measured current, 50 A for 4 s. Overheating of converter B is P0EA6.
